Key result
Combining multi-vendor delivery systems enables LV lead implantation in a massive coronary sinus.
Why the study?
A persistent left superior vena cava draining into the coronary sinus markedly increases its size, complicating left ventricular lead placement in CRT patients.
Case Report (n=1)
Describes a novel interventional approach for LV lead implantation in patients with a massive coronary sinus due to superior vena cava drainage.
No takes yet. Share an insight, caveat, or question.
Anomalous SVC drainage into a massive CS may hinder CRT lead placement; this case leaves open whether multi-vendor systems improve success rates.
Worley et al. (2008) conducted a case report in Drainage of the superior vena cava into the coronary sinus requiring cardiac resynchronization therapy (n=1). Interventional approach to LV lead implantation utilizing a combination of delivery systems was evaluated. An interventional approach utilizing a combination of delivery systems from different vendors enabled left ventricular lead implantation in a patient with a massive coronary sinus.
